*** Official AMD Phenom II X6 1055T & 1090T Overclocking Thread ***

Coretemp is reading 49C (0.95 and 0.96 read the same)
AI Suite is reading 68C

CPU temp is the one you have to watch, not core temps. The 1090T max temp is 62*C. So you are exceeding that by a fair margin. Could be damaging your cpu as a result

And yes that will definetly why it is throttling. Need to sort out some better cooling for your chip and or reduce OC/voltage.

Most of us make sure we dont go over 60*C in stress tests. And less than 50*C for a typical load (encoding etc)

Im having a problem with my 1055T , sometimes it doesnt goto full power mode from its power saving state, its very random.

Heard a few others having the same problem with different motherboards on extreme forums.

Thing is , is it the chip or the bioses? hmmmm
Click to expand...

I think its BIOSes tbh. I dont have the clocking up problem, I have a clocking down problem.

ASUS have made a comment on the official forum for my board, saying that hopefully in future bios release they will fix up and down clocking problems, including giving you the option to force a lock out on the multi.

So i take it then that the temps being reported by the AI suite are correct and that is what you go by ?
See you also have a Crosshair 4.

Certainly explains why i could observe throttling when i shouldn't have according to CoreTemp.

Normal running is 4GHZ like everyone else with vcore at 1.4 under load, seems to have a mind of it's own on the Crosshair though.
Starts at 1.36 and increases under load to 1.4V.
Temps are well under thermal limits then.

What NB volts are you running ?
Tried 3GHZ NB but it needed a large increase in volts and was not that stable.
Certainly IBT wouldn't complete more than 2 or 3 runs

Yeah the temp you need to watch and the temp the BIOS uses for throttling is the cpu temp.

Quite a few other programs report that temp, HWmonitor does, everest does. I cant use PCProbe, its too buggy. Plus everest outputs a load of info to my G15.

Have you tried enabling LLC? (load line calibration) in the BIOS. Means I can set 1.4v to get 4 gHz. Altho in reality it overvolts to 1.44v IIRC. (which is normal for this board, an overvolt of 0.35v for LLC) I used the measure points on the board and compared it the voltage reading in cpu-z while under load and they match up perfectly.

Does it help real world tho?

Also are your sticks/imc stable at 1T or have you upped voltage on one or both.
Click to expand...
tbh i haven't tested the real world performance yet.

my sticks are crap tbh. they are rated at 1600mhz 7-7-7-20 1t or 2t. 1.7v but it's impossible the get them stable at that. 1.75 is better but still not stable. i've tryed upping the cpu-nb voltage way up to 1.35v but still as issues

1333mhz 6-6-6-15 1t 1.7v is fully stable

1.35v
 
I set vcore to 1.3625v in bios with LLC enabled.
Under load monitored in cpuz it reaches 1.404v.

Another annoying thing is the downclocking.

If you do a warm reboot, the CPU clocks down to 800MHZ or so.
It does increase to 4GHZ under load,

If you do a cold boot it runs at 4GHZ all the time, no down clocking when lightly loaded.

ASUS need to sort this out, allthough this seems to be a problem with all boards running X6's at the moment.
My Gigabyte 770 does exactly the same thing.

CPU temp.
I've been doing this for a while :p
Asus Probe does the CPU temp, not the core temp.
As the CPU temp gets higher, the core temp does begin to give a more accurate reading, sometimes higher than the CPU temp (General observation).
Click to expand...
core temp should be always higher than cpu temp. if it's not then its no way need accurate.

This has been brought up on the official ASUS forum already and they are working on a fix afaik. 0801 beta is out, which supposedly improves things with CnQ and C1E. Im a bit reluctant to try a beta tho, hopefully it will be a final release before long.

EDIT:

And with that they release 0707 beta, one the fixes being: "Enable fix CPU multiplier for 6-core processor when disabling [Cool and Quiet] in BIOS". So hopefully in next few days we'll get a main release bios to fix these sorts of issues :)

Why? We dont even know which sensor is which, how they are worked out, if there is a deliberate calibration error to fit in some thermal protection, etc.

Temps are what they are, so long as your in max rating, things are stable etc. What does it matter if they dont seem accurate, thats not what they are there for, they are there to protect the cpu, thats it.

gareth170 said:
only on the latency.
the read / write / copy score will be fast with 1600MHZ 7-7-7-20-2T

but my sticks should be able to do 1600MHZ 7-7-7-20-1T also

Your sticks might, doesnt mean the IMC will :)

:confused::confused:

what do u mean We dont even know which sensor is which???

the temp layout hasn't changed from previous phenoms.

i know, i'm not stupid mate...

and i know for sure it's not the IMC at fault

Ok please tell me exactly where in the real world the "cpu" and "core" temp are being measured from.
Click to expand...

personly i think,

cpu temp is from the sensor inside the chip on the case.

core temp i personly think it guesses the core temp from the cpu temp. thats why some core temps are 1c or 0c and some are way higher than cpu temp.

also amd themselves said cpu temp is the right one

i know amd said its right one, Im just saying to take temp readings with a pinch of salt.

Coretemp gives you the "core" temp, yet goes on about only being one sensor

Amd reply to you saying its not core temp you need to watch.

On Intels, CPU temps is the IHS temp, core temp is exactly that. Seems to be dispute and confusion over phenom II sensors.

That was my meaning behind saying we dont know which is which, cus we cant say for sure exactly where each is being read, can just speculate and hope for best.

Id say as long as both of the two temps are under 62*C stress testing we should be ok.
